C.8.35 Confocal Microscopy Image Modules

This Section describes the Confocal Microscopy Image Module, the Confocal Microscopy Tiled Pyramidal Image Module, and the Cutaneous Confocal Microscopy Image Acquisition Parameters Module.

The Confocal Microscopy Image Module and the Confocal Microscopy Tiled Pyramidal Image Module contain Attributes specific to Confocal Microscopy images.

The Cutaneous Confocal Microscopy Image Acquisition Parameters Module contains Attributes that are specific to Cutaneous Confocal Microscopy images.

C.8.35.1 Confocal Microscopy Image Module

Table C.8.35.1-1 specifies the Attributes that describe confocal microscopy images.

Attribute Name

Tag

Type

Attribute Description

Image Type

(0008,0008)

1

Image identification characteristics.

See Section C.8.35.1.1.1 for specialization.

Photometric Interpretation

(0028,0004)

1

Specifies the intended interpretation of the pixel data.

See Section C.8.12.1.1.1 for specialization of this Attribute.

Bits Allocated

(0028,0100)

1

Number of bits allocated for each pixel sample. Each sample shall have the same number of bits allocated.

See Section C.8.12.1.1.2 for specialization of this Attribute.

Bits Stored

(0028,0101)

1

Number of bits stored for each pixel sample. Each sample shall have the same number of bits stored.

See Section C.8.12.1.1.2 for specialization of this Attribute.

High Bit

(0028,0102)

1

Most significant bit for pixel sample data. Each sample shall have the same high bit.

See Section C.8.12.1.1.2 for specialization of this Attribute.

Pixel Representation

(0028,0103)

1

Data representation of the pixel samples. Each sample shall have the same pixel representation.

See Section C.8.12.1.1.3 for specialization of this Attribute.

Samples per Pixel

(0028,0002)

1

Number of samples (planes) per image.

See Section C.8.12.1.1.4 for specialization of this Attribute.

Planar Configuration

(0028,0006)

1C

Indicates whether the pixel data are encoded color-by-plane or color-by-pixel.

Required if Samples per Pixel (0028,0002) has a value greater than 1.

See Section C.8.12.1.1.5 for specialization of this Attribute.

Lossy Image Compression

(0028,2110)

1

Specifies whether an Image has undergone lossy compression (at a point in its lifetime).

Enumerated Values:

00

Image has not been subjected to lossy compression.

01

Image has been subjected to lossy compression.

Once this value has been set to 01 it shall not be reset.

See Section C.7.6.1.1.5

Confocal Mode

(0048,0114)

1

Whether the images were acquired by the confocal microscope in reflectance or fluorescence mode.

Enumerated Values:

REFLECTANCE

FLUORESCENCE

Tissue Location

(0048,0115)

1

Whether the tissue that is the subject of the image is in the body (i.e., in-vivo) or an excised tissue sample (i.e., ex-vivo).

Enumerated Values:

INVIVO

EXVIVO
